AN INVESTIGATION TO FIND THE EFFECT OF BILE SALTS OF ON THE DIGESTION OF LIPIDS I have investigated that if there is an effect of bile salts on the digestion of lipids in the milk. When lipids are broken down in to fatty acids and glycerol (see below)‚ the acid lowers the pH of the mixture. To help me determine and measure the digestion of lipids‚ a pH indicator phenolphthalein has been used to measure the pH of the mixtures. The pH indicator will change the colour from pink to either white (if

presentation entitled "The Environmental Impacts of Chemical Deicers and Road Salt". I was required to attend this presentation for my Environmental Issues class as well. The presentation was approximately 25 minutes long and included a powerpoint presentation. In the presentation itself‚ it stated the impacts of road salts and deicers‚ the state uses on the roadways during the winter months. The most commonly used road salt is sodium chloride‚ which is also the most inexpensive and readily available

1. What importance have the following groups attached to salt? i. Romans: Romans considered “common salt” a right and used it for cooking in both plebian and patrician cuisine. Salt trade was a prominent way of making money and soldiers were often paid in salt. A tightly controlled monopoly on salt contributed to military funds. ii. Greek Philosophers: Plato describes salt as dear to the gods‚ and we can even see the importance attached to it in religious ceremonies‚ covenants‚ and magical charms

Spilled Salt Rape is a more and more usual in the everyday life. How tragic and hard it is for the victim‚ but what about the criminal’s family‚ friends‚ parents? The shame and quilt one may feel. Unanswered questions‚ how did my son come to this? Why? What will people think? Spilled Salt is a good example of such havoc a rape might leave to the family. Spilled Salt is an American shorty story published by the author Barbara Neely. The story takes place in America where the loving mother‚ Myrna

Introduction: Solubility equilibrium refers to the dissolution of a compound in water. Specifically‚ the degree to which a compound is soluble (Tro‚ 739). This can be measured using the expression Ksp = [Mb+]a[Xa-]b‚ in which Ksp represents the solubility product constant (Thorne‚ 90). This constant is important because it does not change at a given temperature‚ regardless of the solution a compound is in; a smaller constant would indicate lower overall solubility. It is important to note that

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

“Morton Salt“ “No one knows Salt like we do”. Morton Salt generates a never-ending supply of new products in covering all possibilities where salt can be used and is not focusing on only one type of salt e.g. Culinary Salt. During over 160 year’s history‚ Morton Salt never stopped developing new salt products and finding new niche markets. Salt is not seen as a mundane product that is only used to salt e.g. food but even more as science. Morton Salt is presenting on his website how various salt can

Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

SALTS EVERYDAY First some words about salts in chemistry. Salts are ionic compounds that can result from the neutralization reaction of an acid and a base. They are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). Salts can appear to be clear and transparent (sodium chloride)‚ opaque‚ and even metallic and lustrous (iron disulfide). In many cases the apparent opacity or transparency are

Solubility Product Determination Purpose • To determine the solubility product constant‚ Ksp‚ of an ionic compound. Introduction The solubility product constant‚ Ksp‚ is a particular type of equilibrium constant. The equilibrium is formed when an ionic solid dissolves in water to form a saturated solution. The equilibrium exists between the aqueous ions and the undissolved solid. A saturated solution contains the maximum concentration of ions of the substance that can dissolve at
